Source apportionment, ecological and human health risk assessment of potentially toxic elements in Tumet River, Ethiopia.

ABSTRACT: Mining activities are known sources of water pollution by Potentially Toxic Elements (PTEs), and threatening the health of humans and water ecosystem. This study aimed at evaluating the PTE concentrations and sources of PTEs enrichment in Tumet River, and associated human-ecological health risks in children and adults. The concentration of the studied PTEs (9 elements) in Tumet River water were quantified using Atomic Absorption Spectroscopic technique. The average values of the PTEs were found to be 0.02 ± 0.002-43.4 ± 1.4 mg/L, and 0.019 ± 0.001-39.7 ± 0.3 mg/L for dry and wet seasons, respectively. In both seasons the lowest and highest average values were observed for Cr and Fe, respectively. The average PTE concentrations exceeded drinking water (except for Zn and Cr) and ecological q
